Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet synchronous motors, and particularly to a flange detachable integrated permanent magnet synchronous motorized spindle structure. Background Art

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate the rotor magnetic field. The spindle of the permanent magnet motor is usually fixed through a flange. The flange, as the interface between the spindle and external equipment, realizes rapid installation and precise positioning through a standardized connection method, ensuring machining accuracy and stability. Moreover, during high-speed operation, the flange evenly disperses axial and radial loads through structural design, avoiding stress concentration, and enhancing the system rigidity and durability.

[0003] Currently, the flange on the traditional integrated permanent magnet synchronous motor spindle is not detachable. If a failure occurs during use, due to its non-detachability, it is not convenient for maintenance, and the whole needs to be replaced during maintenance, increasing the downtime and economic cost. Also, different specifications of accessories cannot be quickly replaced, restricting the equipment's ability to adapt to multi-task scenarios. In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a flange detachable integrated permanent magnet synchronous motorized spindle structure.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A flange detachable integrated permanent magnet synchronous motorized spindle structure includes a rotating shaft connected to the output end of the permanent magnet motor, and further includes:

[0007] A fixed sleeve fixedly arranged on the outer wall of the permanent magnet motor, and a rotating sleeve is rotatably connected to the fixed sleeve;

[0008] A flange member is installed at one end of the rotating sleeve away from the fixed sleeve. An annular cylinder is provided on the flange member. The rotating sleeve is sleeved on the annular cylinder. Corresponding first clamping grooves are provided on both the flange member and the rotating sleeve, and corresponding second clamping grooves are provided on both the flange member and the rotating shaft;

[0009] A first clamping block is slidably arranged in the first clamping groove;

[0010] A second clamping block is slidably arranged in the second clamping groove.

[0011] Preferably, a round hole is provided on the rotating sleeve. A nut seat is provided on the inner wall of the round hole. A screw rod is threadedly connected to the nut seat. The screw rod is placed in the first clamping groove and is rotatably connected to the first clamping block. When the first clamping block moves towards the side close to the annular cylinder, the rotating sleeve and the annular cylinder can be locked.

[0012] Further, two T-shaped grooves are provided on the first clamping block, and T-shaped blocks are slidably connected in the two T-shaped grooves. Limiting blocks are fixedly connected to the bottoms of the two T-shaped blocks. Bevels are provided at one ends of the two limiting blocks close to the middle of the first clamping block. Elastic members are provided between the T-shaped blocks and the inner walls of the T-shaped grooves.

[0013] Further, a frustum is provided in the first clamping groove. The frustum is fixedly connected to the annular cylinder. The frustum cooperates with the bevel on the first clamping block. A connecting rod is slidably connected to the frustum and the annular cylinder. The bottom of the connecting rod is connected to the second clamping block. When the connecting rod drives the second clamping block to move towards the end close to the rotating shaft, the rotating shaft and the annular cylinder can be locked.

[0014] Further, small holes are provided on the frustum. A circular plate is fixedly connected to the top of the connecting rod. The circular plate can slide in the small holes. Concave holes are provided on the annular cylinder. A spring is provided between the outer wall of the second clamping block and the inner wall of the concave hole.

[0015] Further, two symmetrically arranged circular holes are provided on the rotating sleeve. Screws are provided in the two circular holes. Two first clamping grooves and two second clamping grooves are provided. First clamping blocks and second clamping blocks are arranged in the two first clamping grooves and the two second clamping grooves.

[0016] Further, supporting members are provided on the inner walls of the two circular holes. The screws are rotatably connected to the supporting members. Knobs are fixedly provided at one ends of the screws outside the circular holes.

[0017] Preferably, first mounting holes are provided on the outer walls of the fixed sleeve and the permanent magnet motor. First bolts are connected in the first mounting holes. The fixed sleeve is fixedly connected to the permanent magnet motor through the first bolts.

[0018] Further, an annular plate is provided on the rotating sleeve. A bearing is provided on the annular plate. The bearing is arranged between the annular plate and the fixed sleeve. The rotating sleeve is rotatably connected to the fixed sleeve through the bearing.

[0019] Further, second mounting holes are provided on the rotating sleeve. Third mounting holes corresponding to the second mounting holes are provided on the flange members. A plurality of placing grooves are further provided on the rotating sleeve. The placing grooves communicate with the second mounting holes. Second bolts are connected in the second mounting holes and the third mounting holes.

[0020] Compared with the prior art, the present invention provides a flange-split integrated permanent magnet synchronous motorized spindle structure, which has the following beneficial effects:

[0021] 1. The flange can be disassembled into an integrated permanent magnet synchronous electric spindle structure. By rotating the screw, the screw will drive the first block to move downward when it moves, so that the first block moves to the side close to the annular cylinder. The first block can just resist the gap between the annular cylinder and the rotating sleeve, thereby forming a fixation. At this time, the flange and the rotating sleeve will not be separated, which is convenient for use. By rotating the screw in the opposite direction, the first block can be driven to move upward by the screw. When the first block moves to the point where it no longer resists the annular cylinder, it can be disassembled for easy maintenance or replacement. There is no need to replace the entire block, which reduces labor intensity, improves work efficiency, and saves time and effort.

[0022] 2. The flange can be disassembled into an integrated permanent magnet synchronous electric spindle structure. When the first clamping block moves to the side close to the annular cylinder, it will also press the connecting rod, so that the second clamping block at the bottom of the road moves, so that the second clamping block moves to the end close to the rotating shaft, so that the second clamping block is against the gap between the rotating shaft and the annular cylinder, so that the rotating shaft and the flange are fixed. Under the action of the spring, the second clamping block can also be automatically reset, and no limit operation is formed. At this time, the flange and the rotating shaft can be disassembled for maintenance or replacement. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0035] Embodiment 1:

[0036] Refer to Figures 1-9A flange-detachable integrated permanent magnet synchronous electric spindle structure includes a rotating shaft 101 connected to the output end of a permanent magnet motor 1, and also includes a fixed sleeve 2 fixedly arranged on the outer wall of the permanent magnet motor 1, a rotating sleeve 3 is rotatably connected to the fixed sleeve 2, a flange 4 is installed at the end of the rotating sleeve 3 away from the fixed sleeve 2, an annular cylinder 401 is provided on the flange 4, the rotating sleeve 3 is sleeved on the annular cylinder 401, the flange 4 and the rotating sleeve 3 are both provided with corresponding first card grooves 404, and the flange 4 and the rotating shaft 101 are both provided with corresponding second card grooves 405; a first card block 6 is slidably arranged in the first card groove 404; a second card block 704 is slidably arranged in the second card groove 405.

[0037] In the present invention, during installation, the fixed sleeve 2 is first fixedly installed on the outer wall of one side of the output end of the permanent magnet motor 1, and then the rotating sleeve 3 is installed on the fixed sleeve 2, so that the rotating sleeve 3 can rotate with the fixed sleeve 2, and then the rotating shaft 101 is installed on the flange 4, and the flange 4 is connected to the fixed sleeve 2 and the rotating sleeve 3. In the present application, a first card slot 404 and a second card slot 405 are provided, and a first card block 6 and a second card block 704 are respectively provided in the first card slot 404 and the second card slot 405. When the first card block 6 moves to a position close to the annular cylinder 401, the first card block 6 can just abut against the gap between the annular cylinder 401 and the rotating sleeve 3, thereby forming a fixation. When the second card block 704 moves to a side close to the rotating shaft 101, the second card block 704 can just abut against the gap between the rotating shaft 101 and the annular cylinder 401, thereby fixing the rotating shaft 101 and the flange 4. At this time, starting the permanent magnet motor 1 can drive the rotating shaft 101 at the output end to rotate.

[0038] When maintenance, disassembly or replacement is required, the first clamping block 6 and the second clamping block 704 can be moved in opposite directions. Specifically, the first clamping block 6 is moved toward one end close to the rotating sleeve 3, so that the first clamping block 6 is located in the first clamping groove 404 on the rotating sleeve 3 when it moves. The first clamping groove 404 on the rotating sleeve 3 is set deeper, enough to accommodate the entire first clamping block 6. At this time, the first clamping block 6 will not abut the flange 4, and the flange 4 can be removed; similarly, the second clamping block 704 is moved toward one end close to the annular cylinder 401, and the second clamping groove 405 on the annular cylinder 401 is set deeper, enough to accommodate the entire second clamping block 704. At this time, the second clamping block 704 will not abut the rotating shaft 101, and the rotating shaft 101 can be removed from the flange 4, so as to start the maintenance or replacement operation, without the need for a complete replacement, reducing labor intensity, improving work efficiency, saving time and labor, reducing time and economic costs, and being detachable to facilitate the replacement of accessories of different specifications, suitable for use in a variety of occasions.

[0040] ReferenceFigures 1-9 A flange-detachable integrated permanent magnet synchronous electric spindle structure includes a rotating shaft 101 connected to the output end of a permanent magnet motor 1, and also includes a fixed sleeve 2 fixedly arranged on the outer wall of the permanent magnet motor 1, a rotating sleeve 3 is rotatably connected to the fixed sleeve 2, a flange 4 is installed at the end of the rotating sleeve 3 away from the fixed sleeve 2, an annular cylinder 401 is provided on the flange 4, the rotating sleeve 3 is sleeved on the annular cylinder 401, the flange 4 and the rotating sleeve 3 are both provided with corresponding first card grooves 404, and the flange 4 and the rotating shaft 101 are both provided with corresponding second card grooves 405; a first card block 6 is slidably arranged in the first card groove 404; a second card block 704 is slidably arranged in the second card groove 405.

[0041] A circular hole 5 is provided on the rotating sleeve 3, and a nut seat 504 is provided on the inner wall of the circular hole 5. A screw 502 is threadedly connected to the nut seat 504. The screw 502 is placed in the first slot 404 and is rotatably connected to the first block 6. When the first block 6 moves toward the side close to the annular cylinder 401, the rotating sleeve 3 and the annular cylinder 401 can be locked.

[0042] In the present invention, when performing the fixing operation, after the fixing sleeve 2, the rotating sleeve 3, the flange 4 and the rotating shaft 101 are installed, the screw 502 is rotated to make it threadedly connected with the nut seat 504, thereby driving the screw 502 to move downward. When moving, the screw 502 will drive the first clamping block 6 to move downward, thereby causing the first clamping block 6 to move toward the side close to the annular cylinder 401, and the first clamping block 6 can just abut against the gap between the annular cylinder 401 and the rotating sleeve 3, thereby forming a fixation. At this time, the flange 4 and the rotating sleeve 3 will not be separated, which is convenient for use. Similarly, by rotating the screw 502 in the opposite direction, the first clamping block 6 can be driven to move upward by the screw 502. When the first clamping block 6 moves to the point where it no longer abuts against the annular cylinder 401, it can be disassembled for easy maintenance or replacement.

[0043] Reference Figures 5-9 Two T-slots 601 are provided on the first clamping block 6, and T-blocks 602 are slidably connected in the two T-slots 601. The bottoms of the two T-blocks 602 are fixedly connected to limit blocks 603. The two limit blocks 603 are provided with inclined surfaces 604 on one end close to the middle of the first clamping block 6, and an elastic member 605 is provided between the T-block 602 and the inner wall of the T-slot 601.

[0044] Reference Figures 5-9 A frustum 7 is provided in the first slot 404, and the frustum 7 is fixedly connected to the annular cylinder 401. The frustum 7 cooperates with the inclined surface 604 on the first clamping block 6. A connecting rod 702 is slidably connected to the frustum 7 and the annular cylinder 401, and the bottom of the connecting rod 702 is connected to the second clamping block 704. When the connecting rod 702 drives the second clamping block 704 to move toward one end close to the rotating shaft 101, the rotating shaft 101 and the annular cylinder 401 can be locked.

[0045] In the present invention, when the first clamping block 6 moves towards the side close to the annular cylinder 401, it also presses the connecting rod 702, so that the second clamping block 704 at the bottom of the connecting rod 702 moves, so that the second clamping block 704 moves towards one end close to the rotating shaft 101, and the second clamping block 704 abuts against the gap between the rotating shaft 101 and the annular cylinder 401, so that the rotating shaft 101 and the flange member 4 are fixed.

[0046] Refer to Figure 8 and Figure 9 As shown in Figures 1 and 2, the frustum 7 is provided with a small hole 701, the top of the connecting rod 702 is fixedly connected with a circular plate 703, the circular plate 703 can slide in the small hole 701, the annular cylinder 401 is provided with a concave hole, and a spring 705 is arranged between the outer wall of the second clamping block 704 and the inner wall of the concave hole.

[0047] When the screw 502 rotates in the reverse direction, the first clamping block 6 can be reset and no longer form a limiting operation. At this time, under the action of the spring 705, the second clamping block 704 can also be automatically reset, so that the second clamping block 704 is placed in the second clamping groove 405 on the annular cylinder 401 and no longer forms a limiting operation. At this time, it is convenient to disassemble, repair or replace the flange member 4 and the rotating shaft 101.

[0048] Specifically, when the first clamping block 6 moves, the inclined surface 604 on its limiting block 603 will contact the frustum 7. After the conical surface on the frustum 7 contacts the inclined surface 604, it will push the limiting block 603 to move, so that it moves to both sides of the first clamping block 6, so that the two limiting blocks 603 can protrude, and both ends thereof will abut against the inner wall of the first clamping groove 404, so that the first clamping block 6 is fixedly connected, improving the connection stability. The T-shaped groove 601 and the T-shaped block 602 are provided to make the movement of the limiting block 603 more stable, and the elastic member 605 is provided to make the T-shaped block 602 automatically reset after moving, facilitating repeated use. The elastic member 605 can specifically adopt a spring or the like.

[0049] Refer to Figures 5-9 As shown in Figure 3, there are two symmetrically arranged circular holes 5 on the rotating sleeve 3. Screw rods 502 are arranged in both of the two circular holes 5. There are two first clamping grooves 404 and two second clamping grooves 405. The first clamping block 6 and the second clamping block 704 are arranged in both of the two first clamping grooves 404 and the second clamping grooves 405.

[0050] The inner walls of the two circular holes 5 are also provided with support members 501. The screw rod 502 is rotatably connected to the support member 501, and a knob 503 is fixedly arranged at one end of the screw rod 502 outside the circular hole 5.

[0051] In the present invention, by providing two sets of first card slots 404, second card slots 405, first card blocks 6 and second card blocks 704, the two sets can cooperate and fix with each other, thereby improving the fixing effect. By providing the support member 501, the screw 502 can rotate more stably, and the provided knob 503 can make it more convenient to rotate the screw 502, facilitating use.
